Lots of top vintage and contemporary pieces are included in the many images added to the site this month. Formats for the 19th-century work posted up range from daguerreotypes to stereos to cartes-de-visite to larger salt and albumen prints. Some of the important 19th-century photographers whose work has been posted include: Gustave de Beaucorps, Giacomo Caneva, Francis Frith (mammoth plate of Cairo), Andreas Groll, Hill & Adamson, Baron Louis-Adolphe Humbert de Molard, Charles Marville, Eadweard Muybridge, Charles Negre, Shimooka Renjô and Baron Raimond Von Stillfried, among others.

Charles Schwartz Ltd. has added a new special exhibit on 19th-century Japanese ambrotypes (late 1860s-1890), which you can see here: http://www.iphotocentral.com/showcase/showcase_view.php/39/3/1 . These rare, one-of-a-kind images were created by Japanese photographers for Japanese clients, which was a shift from earlier photographs made in Japan by Westerners and for Western consumption. Culled from villages and remote family collections, these portraits were made as personal keepsakes and intended to be passed-down as precious heirlooms. Of particular note is a portrait of a Samurai whose name is known (CS8994). Prices range from $300-$6,500. In addition numerous other 19th-century Special Exhibits have been revised. You can see the rest of the Special Exhibits here: http://www.iphotocentral.com/showcase/showcase.php .

Top pieces by contemporary artists, including Peter Beard, Robert Mapplethorpe, David Hockney, Marcus Leatherdale, Kim Joon and Nobuyoshi Araki, have also been put up on the website.

And numerous images that will knock you out from lesser known or anonymous photographers, plus some scarce photographer-signed books. There's something here for every budget.

We have also continued to change out images and add to our essays for all our Special Exhibits, so they are worth another peek, especially if you have not looked lately. If you see one you like, let a friend know too! And don't be afraid of posting them up on your Facebook or LinkedIn pages.
